I thought my brother then the kids from his class came to me to tell me my brother became a bully and was abusing his power then I came to my brother and told him that if I hear again that he was bullying other kids that I will beat him my self....then he stopped bullying kids and I stopped teaching him. I felt responsible cause I made a pledge to God never to hurt people with what I know from martial arts so I don't like other people hurting other people
